The facts behind the Superstorm
.......This interglacial is now ending, and human activity has added so much CO2 to the atmosphere that the change of climate that will now take place is going to be extremely violent, probably much more so than in the past. In addition, we may not experience the onset of a new ice age at all, but the 'locking' of the climate into a much hotter pattern until the excess CO2 dissipates. This will not happen until human activity is reduced by negative natural events.
Millions of people have already suffered from the effects of sudden climate change. A great American city has been ruined. Billions more stand to lose their lives over the next twenty years. A combination of rational disaster planning worldwide and an aggressive effort to reduce CO2 emissions as quickly as possible are now essential to minimize loss of life and disruption. If these things are not done, the present planetary economy and the civilizations that it supports will cease to exist.
